#### Spline

GameObject with the CurvySpline component attached

#### Control Point

A point controlling a spline's curvation (sometimes called “Node” by others). Curvy's Control Points are regular GameObjects with the CurvySplineSegment component attached, always child objects of a spline and automatically managed.

#### CG

Abbreviation for Curvy Generator

#### CP

See Control Point

#### Tangent

The Tangent vector is the (normalized) direction of a spline point

#### Up

The Orientation- or Up-Vector defines the Upside of a spline point. Together with the Tangent it forms the rotation used by controllers for a given spline point

#### Total Fragment

A relative position on the spline, ranging from 0 (start) to 1 (end) This is the “time” parameter used in the splines' formulas. A point's TF is not proportional to its distance from the spline's start. Depending on the spline, a value of 0.5 does not always mean the middle, distance wise, of the spline

#### TF

See Total Fragment

#### F

A relative position on a spline segment, ranging from 0 (start of segment) to 1 (end of segment) F is not proportional to its distance from the segment's start. Depending on the spline, a value of 0.5 does not always mean the middle, distance wise, of the segment

#### Orientation Anchor

Used by dynamic Orientation mode, this Control Point option tells Curvy to use the transform rotation of the Control Point as an orientation target. Think of “orientation” waypoints.
